1. WF on Supporting different Numerologies in a NR carrier LG Electronics, [Huawei, HiSilicon, Panasonic], 3GPP TSG RAN WG1 Meeting #85R1-165837 Nanjing, China, 23th – 27th May 2016 Agenda Item:7.1.1 1

2. Background Agreements from Tuesday: – Forward compatibility of NR shall ensure smooth introduction of future services and features with no impact on the access of earlier services and UEs Multiplexing different numerologies within a same NR carrier bandwidth (from the network perspective) is supported – FDM and/or TDM multiplexing can be considered 2

3. Proposal Contiguous frequency resources using one numerology set in a NR carrier is called ‘FRG’ – A numerology set is defined by CP duration and subcarrier spacing – One numerology set is applied in FRG over T time duration FFS on details of T – Multiple FRGs in a NR carrier with different numerologies is supported – Multiple FRGs in discontinuous frequency resources in a NR carrier can use the same or different numerology set – FFS sizes of FRG whether FRG (e.g., size of FRG and T) can change dynamically or semi-statically. whether different FRGs can overlap or not whether/how to handle DC subcarrier aspects in a NR carrier comprising multiple FRGs – FFS: NR supports the following Each FRG has its own synchronization signal(s) Multiple FRGs share the same synchronization signal(s) 3
